I use a track called "Guided Meditation" by Kelly Howell. I downloaded it off of iTunes, though you may be able to find it free online somewhere. I just lay back and put my ear buds in and relax. The track is about 30 minutes long and uses special sounds that are said to affect your brain waves, and Howell instructs you and uses visualization techniques. I find it to be very fulfilling; I too deal with lots of stress and anxiety.
